5. Transport, packaging and storage
5.1. Transport
Check if the micro calibration bath shows any damage caused during transport. Report evident
damages immediately.
5.2. Packaging
Do not remove the packaging until just before installation.
Keep the packaging as it is the ideal protection during transport (e.g., if the installation site changes or if
the product is shipped for possible repairs).
5.3. Storage
Permissible conditions at the place of storage
Storage temperature: -10 ... + 60ºC.
Humidity: 30 ... 95% RH (non-condensing).
Avoid the following
Direct sunlight or proximity to hot objects.
Mechanical vibration, mechanical shock (sudden standing).
Soot, steam, dust and corrosive gases.
Potentially explosive environment, flammable atmospheres.
6. Commissioning, operation
6.1. Checking the temperature sensors
To check the temperature sensors, connect a measuring instrument distinct of the checking sensor. By
comparing the temperature indicated on the external measuring instrument with the reference
temperature, you can check the status of the checking sensor. Watch that the sensor requires little time
to reach the temperature.
WARNING
Thermocouples with grounding cannot be calibrated because they are grounded, so
measurements could lead to erroneous results.
6.2. Starting Procedure
If the calibrator is not used for a long period, it is possible that moisture penetrates in the heating towers
due to the materials used (magnesium oxide). After transportation or storage of micro-bath in humidity
environment, heating towers must be preheated slowly. During the drying process it is assumed that
the micro-bath has not yet reached the required isolation voltage for the protection class.
6.3. Starting the Micro calibration bath
1) Connect the instrument to the power.
2) Press the switch on. The controller is activated.
3) After about 30 seconds, activation has been completed and the calibration mode is automatically
displayed. Mounted heating and cooling towers, regulate micro-bath
’s
temperature
to match the
adjusted nominal temperature on the controller.
4)
Activate the magnetic stirrer bar using the potentiometer, turning it to the right completely (100%).
